I was asked how to make the crib rail covers as seen here:
I basically googled how to do it and went from there. I can't remember which site it was now, but below are a couple of links with similar ideas. Each crib could be slightly different, so my advice is measure yours and adapt the pattern to your situation. I did not use velcro as our little man can take off his bibs now when they have velcro so he would figure out how to remove the crib rail protector. I was going to use snaps but I didn't have enough material, so ribbon/twill tape it was. We'll see how that lasts!!
